Not quite true. It IS a bit of a chore.

	1. Set the Composer pull dow to "Plain text"
	2. DO NOT use a signature which includes an HTML variant

In the Composer prefs panel set these:

	3. "Preview: Display" to "when generating HTML"
     (This assures that you will KNOW if you're generating HTML)
	4. "Rich Text(HTML): Markup syntax:" to "None"
	5. "Default theme is" to "None"
	6. "Highlight code using" to "Nothing"
	7. "Math language" to "None"
